Filed July 20, 1959, Ser.No. 828,157 2 Claims. (Cl. 9-310) This invention relates to animprovement in a boating device and more particularly to a surfboardtype of boating device having a longitudinal and transverse taperresulting in an edge portion of small dimension giving the device anunusual degree'of maneuverability. There are many commonly used similartypes of boating devices which have longitudinally tapered upper andlower surfaces but which are provided with vertically disposed sideportions of some width which side portions substantially reducemaneuverability.

It is desirable to have a device having its upper and lower surfacetapered longitudinally and transversely providing a substantially knifelike edge portion thereabout whereby such a craft may easily skim thesurface of water or skim along just below the surface of water and bewell adapted for slicing through the water in making sharp turns.

It is therefore an object of this invention to provide a boating deviceof the surfboard type having both a longitudinal and a transverse taperresulting in a knife like edge portion there about.

It is another object of this invention to provide a sur-f-' board typeof boating device tapering in width from the front to the rear andhaving both a longitudinal and transverse taper respectively in itsupper and lower surfaces to provide an edge portion of small dimensionthereabout.

It is a further object of this invention to provide a surfboard type ofboating device comprising a pair of mating plate-like membersrespectively having their surfaces tapering longitudinally andtransversely towards the sides and the ends thereof from center pointsthereon resulting in a substantially knife like edge portion thereaboutand a pair of transversely spaced non-skid foot pads molded in onesurface thereof to be flush with said surface.

4 3,@5ii,75l Patented Aug. 28, 1962 being substantially rectangular inplan comprising an elongated plate member 11 forming the upper surfacethereof and a mating plate member 12 forming the lower surface thereof.Thus, said device is formed as a shell having a small central verticaldimension. Said device as formed has a substantially rounded front endportion 13 and a substantially rectilinear central rear end portion 14having rounded corners 15 and 16 at either side thereof.

Said layers 11 and 12 may be formed of various suitable materials. Ithas been found desirable to mold said layers of a fiber glass materialwhich provides substantial rigidity and has a tough resilience making itwell adapted for hard usage and is airtight whichresult's in applicants,7

device being a buoyant light weight structure.

Said layers '11 and 12 are respectively adapted to have a convex taperfrom their central portions to their peripheries forming convexsurfaceslongitudinally and trans verselythereof whereby the mating edgesof said members 7 it and 12 form a substantially knife like edge portionhavmately of an inch. The rear" end edge portion 21 has a radius ofapproximately A: of an inch which tapers to the dimension of the sideedge portions 19 and 2d.

Said layers 11 and 12 are held supported in their tapered i spacedpositions by transversely extending struts'24, 25, Said transverselyextending struts are held secured in position'in their spaced relationto one another It is more specifically an object of this invention topro vide a surfboard type of boating device forming a completelyenclosed shell having an upper and lower surface, said device having asubstantially rounded front edge portion and substantially roundedcorners at the rear end thereof, said device tapering in width from thefront to the rear thereof and tapering longitudinally and transersely ateach surface respectively from central points thereof to provide an edgeportion of small dimension thereabout, a pair of transverse non-skidfoot pads on one of said surfaces embedded to be flush with said surfaceand means in connection with said device to aid in supporting anoperator thereon.

These and other objects and advantages of the invention will be fullyset forth in the following description made in connection with theaccompanying drawings in which:

FIG. 1 is a top plan view of the applicants device;

FIG. 2 is a View in longitudinal vertical section;

FIG. 3 is a view in transverse vertical section;

FIG. 4 is a broken view of an enlarged scale in a vertical section takenon line 44 of FIG. 1 as indicated by the arrows;

FIG. 5 is a broken view on an enlarged scale taken on line 5-5 of FIG. 1as indicated by the arrows; and

FIG. 6 is a broken view on an enlarged scale in vertical section takenon line 6-6 of FIG. 2 as indicated by the arrows.

In the drawings, like reference characters are used throughout theseveral views to indicate identical parts.

Referringto the drawings, applicants boating device 10 is indicated.Said device may be variously formed. In the present embodiment,applicants invention is shown as by the longitudinally extending struts30 and 31 which 'will' respectively intersect and hold in position saidtransversely extending struts. Said struts may be formed of any suitablematerial such as laminated plywood which has been found to be verydesirable for this purpose. Applicants device in being formed offiberglass, has said struts somewhat embedded in the inner sides thereofwhich is done during the molding process of said device. Said strutswill conform in shape to the contour of said members.

Formed integral with the member 11 and embedded therein are thetransversely spaced elongated foot pads 35 and 35 which are formed tohave a non-skid surface to form a gripping surface for the feet of theoperator. The surfaces of said foot pads 35 and'36 are flush with thesurface, of said member 11 so there will be no danger present to thepart of the operator such as of a stubbing of the foot. Said foot pads35 and 36 may be variously formed but are here indicated as having aroughened or embossed surface.

Said upper member 11 has a pair of spaced apertures 40 and 41 at oneside of said device 19 as indicated in FIG. 1 and a second pair ofapertures 42 and 43 at the free ends and a bar type handle 46 is formedat the closed end of said cable. The length of said cable is easily ad-'justed.

Applicants device is here indicated as being formed as a molded devicebut may be otherwise formed as may be desired. The principal area ofnovelty lies in the configuration of the applicants device. Theapplicants device as constructed has light weight and substantialbuoyancy. A specimen of applicants device having a length ofapproximately six feet and a width of thirty inches at its front endtapering to a width of 26 inches at its rear end was formed to haveaweight of approximately thirty-five pounds and this supports a weight ofpounds thereon,

it then being barely submerged beneath the surface of the water. Thrsdevice with it's tapering construction forming a relatively thin edgeportion thereabout is particularly adapted for skimming through theWater very nicely and its knifelike front side edge portions 13b and 130along with the thin edge portions'19 and 20 permit applicants device toslice through the water in being turned very sharply either to the leftor to the right.

Thus, it is seen-that I have provided a very compact and efiectivelyformed surfboardtype' of boating device tor-skimming through the wate'rand for very easily turn- "ing sharply therein. Applicants devicehasjbeen thoroughly tested and has been found to perform satisfactorily..It will," Qf course, be understood that various changes may be madeiinthe formydetails, ar'rangernent,-and proportions of the partswithout'departing front the scope of applicants invention, which,generally stated, consists in a device capablelof carrying out theobjects above set forth,
